what are the advantages and disadvantages of sand casting?
any ideas??
Okay here they are :
Advantages :
1- Low Cost
2- No skilled operators needed
3- Equipments are cheap and easy to deal with.
4- Suitable for few small production rates
5- Can produce large (very large) castings (i.e. Pit casting >> in a very large whole in the ground the molten metal is poured)
Disadvantages :
1- bad surface finish, due to sand indentation and oxidizing medium ..etc.
2- Many defects arise in the casting (no good control on the process , die casting is much better)
3- Not suitable for mass production, oftenly used to produce few number of products compared with other casting proccesses which produce thousands and millions.
4- Dangerous operation , may cause harmful injuries ..etc.
This is what come to my mind, but certainly you could get more from books and other sources
Good luck

Pro’s
Cheap to make the cast (good for prototypes / one offs)
Relatively easy and quick to make the cast
No wasted material when the cast has been used (the sand can be used to make another cast)
Cons
Poor surface finish
Only good for basic shapes
Can usually only be used once
Accuracy of casting sizes aren’t great.
